Hearing Aids Could Have An Additional Benefit, Protecting Against Dementia
With more and more of the aging population having their hearing tested and then opting to wear hearing aids, there is apparently an added advantage – apart from improved hearing.
What did researchers discover?
Researchers have found that those who wear a hearing aid for age-related hearing problem can benefit from better short-term memories and improved concentration.
They came to the conclusion that, after two years of wearing a hearing aid, a person’s ability to concentrate was approximately eight years younger than if they had not worn one. They managed to avoid accelerated aging of the brain. Such aging is associated both with hearing loss and an increased risk of dementia.
The wearing of a hearing aid can actually protect the brain – and reduce the risk of dementia.
Why is the risk of dementia reduced?
The researchers are not 100% sure but have come up with some theories:
- It could be because improved hearing helps the wearer of the hearing aid(s) to participate more in their surroundings, helping to stimulate the brain.
- It could be biological or it could be more social. Hearing loss contributes to social isolation and depression, two of the risk factors for dementia.
How was the research carried out?
Headed by Professor Clive Ballard, from the University of Exeter in the UK, the researchers measure the participants’ concentration levels by using a number of online tests – including pressing a key when the word “yes” appeared on their screen at brief and unpredictable intervals.
The research also involved King’s College in London and their findings were presented at the Alzheimer’s Association International Conference recently in Los Angeles.
Professor Ballard summed up their research by saying: “We know that we could reduce the risk of dementia by a third if we all took action from mid life. The message here is that if you’re advised you need a hearing aid, find one that works for you.”
Some natural ways to try and prevent dementia
Of course it is not likely that we are all going to be wearing hearing aids as we grow older. And too often, pharmaceutical companies, governments and charities are placing the emphasis on treatment rather than prevention in the first place. But there are other ways to help lessen the risk of dementia:
Vitamin D – Recent studies have emphasised the importance of daily vitamin D supplementation to ward off dementia because it has been found that those over the age of 60, and who have a vitamin D deficiency, experience quicker mental decline – as much as three times faster than those with adequate readings. Their other findings include (a) that Vitamin D has a major impact on brain function and (b) those with low levels experience cognitive decline at faster rate.
Regular walking – Helps to keep the brain sharp while walking and is associated with a decrease in Alzheimer’s, dementia, memory loss and other forms of mental decline. A common goal in walking is aiming to achieve some 10,000 steps per day (roughly 4 to 5 miles) which accumulates gradually as you go about your normal errands and activities. Normally, a mile takes about 2,000 steps to walk, so you can increase your distance slowly as you move toward a higher step goal.
Cholesterol – and how we all need sufficient levels to enable our brains to function properly. Cholesterol is a major constituent of the human brain, and the brain is the most cholesterol-rich organ. Cholesterol is tightly regulated between the major brain cells and is essential for normal brain development. Consider the race to lower everyone’s cholesterol and whether this could be part of the reason behind increased Alzheimer’s figures?
Adding coconut oil to your diet – Take two tablespoons daily with food but start off with just a teaspoon of coconut oil and build it up gradually.
Getting sufficient sleep every night – Sleep has always been known as a restorative and healing tool. But of course to make that tool work correctly, you will need a really good night’s sleep. As if to emphasize the importance of restorative sleep, researchers have now discovered that too little sleep could cause brain damage and even accelerate the onset of Alzheimer’s.
